The answer should be C. <span>Im not 100% sure though. the geosphere makes up the earth and its atmosphere as the lithosphere and its hydrosphere. </span>
Topographic maps and satellite images
Explanation:
A topographic map represents earth's surface features like land forms and structures, rivers and lakes, mountains and hills, elevations and other natural features along with man-made artificial features like cities, buildings, monuments, roads, bridges etc. These are formed by contour lines.
Topographic maps are printed with revision dates to observe the changes happening on the Earth's surface. Various land forms keeps changing due to natural and man-made causes and these needs to be updated accordingly to provide accurate details.
A satellite image provides details of the earth aerially from space. These provides details of a land form or any earth structure currently.
By comparing with older satellite images or topographic maps with the current one, the changes which occurred over time can be observed.
Answer:
F1 Females - all wild type
F1 Males - all wild type
F2 Females - - all wild type
F2 Males - 1/2 wild type, 1/2 vermilion
Explanation:
The wild-type allele (Xᵛ⁺) is dominant over vermilion (Xᵛ), which is a sex-linked trait.
Female flies have two X chromosomes, male flies have one X and one Y chromosome.
A homozygous wild-type female fly (Xᵛ⁺Xᵛ⁺) is mated with a vermilion male fly (XᵛY).
The female parent can only produce Xᵛ⁺ gametes.
The male parent can produce either Xᵛ or Y gametes.
When gametes from both parents fuse, the F1 offspring will have the genotypes Xᵛ⁺Xᵛ (females with wild type eyes) and Xᵛ⁺Y (males with wild type eyes).
The F1 females can produce Xᵛ⁺ and Xᵛ gametes. The F1 males can produce Xᵛ⁺ and Y gametes.
When the F1 individuals interbreed, the gametes combine to give rise to the F2 offspring. The possible combination of gametes that will give the different genotypes and phenotypes in the F2 are:
- Xᵛ⁺Xᵛ⁺ females with wild type eyes
- Xᵛ⁺ Y males with wild type eyes
- Xᵛ Xᵛ⁺ females with wild type eyes
- Xᵛ Y males with vermilion eyes
Well, not exactly like some parents have blue eyes and they have a dominant brown eyed child. This can happen because of the gynotype. The history of the child’s parents probably have some brown eyes which caused the child to have brown eyes. But usually the parent does express a dominant trait like the child.
